I had a sleep study done and they said I grit my teeth 16 times and every time I did it I woke up. My doctor today put me on elavil, but isn't this for depression? /and does it work for this problem? Has anyone been on this stuff before? /or is on it now that can tell me if it is good or not? He had me on ambien and took me off and put me on this stuff. Does this make any sense? I am taking Zoloft already for depression so why is he putting me on this too? I know I am asking so many questions I should have asked him, but I didn't know what it was until I got it. I thought it was another type of sleeping med.
